Abstract

The present invention relates to a trapezoidal nut made of sheet metal, proportionally folded under a bend angle to form two parts, with a threaded hole and spikes on one side and a smooth surface hole on another side. The purpose of the invention is to add the ability to attach any object to a nut without compromising its integrity and general purpose, and reliably use a nut without spontaneous unscrewing and detachment from the mounting plane. The goal is achieved by the fact that the trapezoidal nut is fastened with a use of a threaded hole and fixed to be in a static position, with the help of spikes. The smooth surface hole can be used for any purpose at the discretion of the user. The result of the work of the trapezoidal nut is a reliable fixation (without unwanted unscrewing) on a flat surface and the ability to tie or hock anything or any means attached to it.

Claims (5)

1. A trapezoidal nut formed from a single piece of trapezoidal shaped sheet metal consisting of: a first side part, a second side part, and a right angle bend between the first side part and the second side part forming a substantial L-shape; the first side part includes a threaded hole; the second side part includes a non-threaded hole; the first side part includes two first spikes at corners distal from the bend which are formed by deforming the corners; the first side part includes two second spikes at lateral edges of the first side part adjacent the bend which are formed by deforming the lateral edges; the first and second spikes project in a direction opposite the second side part.

2. A trapezoidal nut according to claim 1 wherein the first side part has a trapezoidal shape.

3. A trapezoidal nut according to claim 1 wherein the second side part has a trapezoidal shape.

4. A trapezoidal nut according to claim 1 wherein both the first side part and the second side part have a trapezoidal shape.

5. A trapezoidal nut according to claim 1 wherein the threaded hole is formed by drilling and cutting the thread.
